SPECIFICATION forming part of Letters Patent No. 385,895, dated July 10,1888.

Application filed Decemberl i, 1887. Serial No. 257,891. (No model.)

To aZZ whom, it may concern:

Be it known that we, SOLOMON A. \Voons and JOHN R. THOM.\.s, of the cityof Boston, in the county of Suffolk and State of Massachusetts, haveinvented a certain new and use ful Improvement in Planing Machines, ofwhich the following is a specification.

Our invention relates to planing-machines; and it consists in certainnew and useful constructions and combinations as an improve ment uponthe mechanism for which Patent No. 364,743 was granted to S. A. \Voods,June 14, 1887, substantially as hereinafter described and claimed.

In the drawings, Figure l is a side elevation of a planing-machinecontaining our improve ments. Fig. 2 is a top plan view of the same.Fig. 3 is an enlarged view of a portion of Fig. 1. Fig. 4 is an enlargedview of a portion of Fig. 2.

This machine is intended to form a. tongue or tongues on the edge of theboard by means of horizontal cutter-heads projecting from the sides ofthe bed of the machine above and below the latter, and provided with thenecessary adjusting attachments for the same; and this inventionconsists in an improved method of mounting said horizontal cutter-headsand connecting said adjustments thereto.

A is the frame of the machine. Bis the up per cylinder. B is the lowercylinder. F F F F F F are the feedrolls. 0 O are the side cutter-headsfor forming the grooves in the outer edges of the boards. D is theremovable central guide,which, with the side guides, c" c", is used toguide the lumber through the machine. These and other common andwellknown parts of the machine are constructed substantially as shownand described in said former patent, and need not be more particularlydescribed. The guide D, extending longitudinally through the center ofthe machine, separates the two boards which are being simultaneousl ytongued and grooved, the cutter heads EEsimultaneously forming thetongues on the inner edges of the boards on each side of the centralguide, substantially as in the said lVoods patent.

The horizontal cutterheads E E, which form the tongues, are placedbetween the first pair of feed-rollers F F and the upper cylinder on thefeed-in side of the latter, E being the upper head, and E the lower.Their location in this position enables the main cylinders to remove anyroughness and splinters from the surface of the board which thesetonguing-cut ters may form in cutting the tongue. As they mustnecessarily, when located in this position,

be quite near the main drivingshaft s, from which they are belted, whichis located at the fcedin end of the machine, it is found that theadjustment of these heads vertically to vary the size of the tongues andfinish the edge of the board alters the tension of their drivingbelts.\Ve therefore overcome this difficulty by mounting them on inclined.ways 0 c, placed at such an angle to the shaft 8 as to cause the belt toremain substantially at the same tension as the heads are adjustedvertically, the ways 0 having the upper cutterhead, E, 0 mounted uponthem, and the ways 0 the lower one, E. These ways 0 care formed onbrackets m m, extending upward and downward from and bolted to the mainframe A. The inclined ways 0 on theirbracket m are attached 7 5 to andproject upward from one side of the main frame A, while the inclinedways a on their bracket project downward near the other side of themachine.

The cutter-head E is mounted on shaft 8 which projects inward from oneside of the machine and passes through bearings in the block or slide 0,in which it revolves. This slide is fitted toits ways a, and slides upand down upon them to adjust the cutter-head E 8 vertically. Thecutter-head E is mounted upon the horizontal shaft 8 which projectsinward above the bed from the opposite side of the machine, and passesthrough bearings in the block or slide 0. This latter slide is 0 mountedon horizontal ways in the slide 0 and is adapted to move horizontallytherein. This horizontal adjustment is only sufficient to enable thecutters on head E to be brought exactly over those of head E, thussaving the time required to adjust these cutters in the heads accuratelyby hand. These cutters must, of course, out the upper sides of thetongues on two boards on each side of the con tral guide, D, asdescribed in said patent to me \Voods, and the opposite side of eachtongue must be of exactly the same depth, which is attained by theforegoing adjustment. The slide 6" is mounted upon the inclined ways 6,to which it is fitted by a suitable slot or groove so as to move up anddown thereon. The upand-down movement of the slide 6 upon the ways 6 isregulated by a screw, 1'', which is journaled and revolves in a lug, iprojecting from bracket m, and has its thread tapped through a lug, 2'projecting from the slide e On the upper end of this screw is abevel-gear, i, which serves to revolve it by means of the bevel'gear iupop shaft 8 This shaft projects beyond the front side of the main frameand is squared on the end (see Fig. 4) to receive the crankwrench o(Shown in Fig. 2.)

The movement up and down of the slide upon its ways 6 is controlled by asimilar upwardly-projecting screw, i, journaled in lug 0" upon bracketm, and havingits thread tapped through lug 1'" upon slide 6. The lowerend of this screw is provided with a bevel-gear, i, which engages withthe bevelgear i upon the shaft 8. This shaft projects beyond the sameside of the frame, which supports it by suitable bearings, and is alsosquared at its outer end to receive the crank- Wrench, if desired.

Pinions 12 p are attached, respectively, to

shafts 8'' 8 so that an adjustment of one slide,

6, will adjust the other, e, or vice versa, if desired, by means of athird pinion, 19 meshing into them, as shown in Fig. 1 but this thirdpinion may be removed and shafts s" s separately revolved, if preferred.

The slide 6 has projecting from it a lug, o,

' in which isjournaled the horizontal screw 0,

having hand-wheel 0?. The thread of ,this screw is tapped through thelug 0 which is attached to theslide c. This affords adjustmenthorizontally and longitudinally of shaft s for the slide 6 andcutter-head E, to bring it into proper position with cutter-head E. Arock-shaft, R, isjournaled in the lug 0 and in another lug, 0, uponslide e. Upon it is attached the horizontal arm r, provided with aweight upon its outer end, and a finger, r, which bears against the faceof slide 6 and holds it from dropping down. Pressure-fingers r r arefirmly attached to this rockshaft and curve downward and forward in thedirection in which the lumber is fed under the cutter-head E, on eachside of the path of its knives, over the bed of the machine in positionto bear upon the boards upon each side thereof. These pressure-fingersare attached to rock-shaft R by collars and set-screws 1- W, byloosening which the fingers may be set higher or lower with relation tothe bed. These pressure-fingers of course bear upon the boards on eachside of the guide D as the two boards pass through on opposite sides ofthe guide, as before described.

The bed is formed of a plate, F, which is secured by screw-bolts to thecross-girt f of the frame, and has an opening,f, formed in it, throughwhich the knives of the cutter-head E work in cutting the tongue. Thisplate or bed F may be removed to givebctter access to the knives of thelower cutter-head.

It will be observed that the pressure-fingers r 1- are capable ofindependent adjustment to suit different thicknesses of boards beingsimultaneously worked,'and that they are also adjusted simultaneouslywith the cutter-head E; also, that the construction of the shafts of thecutter-heads E E and attaching parts so that they project from differentsides of the machine gives great facility of access to the working partsfor adjustment and in belting to the drivingshaft. For this purpose thepul ley P is attached to the outer end of the shaft 8, and the pulley l?to the outer end of the shaft s outside the maehineframe. The pulley Pon the driving-shaft sis belted to the pulley P by a straight belt, andthe pulley P on the same shaft is belted to the pulley P by across-belt, as shown in Fig. 1. Both the pulleys I P are thus broughtcloser in toward the frame of the machine than when both of them arelocated on the same side of the machine and belted to the same shaft 8.

The employment of the presser-finger r between the guides e and D of themachine is especially important in insuring the formation of a tongue onthe board which shall fit the groove made by the side cutter-head, C, ina preceding board, because any lifting action of the cutter-heads E Etends to vary the width of the board as well as the shape of the tongueand to draw the board away from the side cutter'head.
